The guy hasn't asked whether he should pay for a rating or not - just an opinion on which rating he should do.
Look at the operators in the area you want to work and the types they operate, then target that market. I know ryanair aren't particularly popular, but it is a start and an opertunity at command within a few years. ( I don't work there by the way! )
If I was doing it again think I'd go for ATR 42/72 or Embraer 145/195. Failing that 787!!!
